Good app and product, but have a request

I like the camera and the app. I have a couple similar products from competitors and a professional model as well. The image processing is very nice and the high refresh rate is a great feature. The request I have, however, is to please allow separate font colors for the high and low temperature readings. And also allow a larger font. It’s is difficult to pick one color that is easy to read against both hot and cold targets. Otherwise no other issues so far.

Nice features, just want a small adjustment

The app has all the features I need: exporting excel temperature data, taking a burst of images every couple of seconds (adjustable from 1 to 3 seconds), setting automatic calibration, custom ambient temperature and emissivity corrections.

My primary ask (thus 4 stars) is this: allow a larger number of images in a burst (max is 10). My application requires at minimum 20 images in a burst with a 3 sec interval. It’s awesome this feature exists at all! A maximum of say, 80 images would be great.

Also, because I need so many images it would be convenient to do a bulk export of temperature data for a set of selected images.

It is great that the file name for the excel data has date and time.

Easy to download and install, once I opened the app and plugged my top Don tcview infrared camera with the extension cable, my phone asked me to put in my password and it took a second for it to recognize the device and it started working. Quite simple. I guess somebody who has had issues with this needs to clean their charge port.
